Heh..So I was right..:) ( eagle eye) ^^ happy for you really nice TB u have there..:)
As for what to do with them..leave them in the tank..now that u know u have hybrids u can start to build tb colony '' from scrach'' ^^
I can't tell for sure cuz of the picture quality but I would say those two black look a lot like taiwan bees, You are sure that u got 100% clean CRS and not some hybrids?
